VISIE.

Application led August 23, 1920. Serial No. 405,275.

T all w hom it may concern Be it known that I, FRANK DANrELsoN, acitizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented a certain new and usefulImprovement in Vises', of which the following is a full, clear, concise,and exact description, reference being had to the accompanying drawings,forming `a part of this specification. v

This invention relates to vises and more particularly `to a vise that isadapted for securely holding various automobile parts without any damagethereto, such for example as pistons,cam shaft bearings, bearing caps,reverse gears, etc;

It is a purpose of the invention to provide a vise that is particularlyadapted for holding Ford cam shaft bearings so that the same will not bebent out of shape while reaming the same. It is'also a'purpose of theinvention to provide suitable means for holdingbearing caps tightly inposition in said vise.

It is a further purpose of the inventionto provide suitable means on avise of this character to prevent a reverse gear from turning in saidvise, said meanscomprising a suitable lug or pin on the rear of saidvise adapted to engage certain portions of said reverse gear to hold thesame, said lug or pin being movable into and out of operative position.V

It is a further purpose of theinvention to providey a suitable guide forfiling valve stems in said vise. To accomplish this purpose the vise isprovided with an operating cam having Va hollow hardened pivotV pinserving as a guide for this purpose. It is suitable means for clampingthe valve in position .in said hollow pin for tiling.

Other objects and advantages vof the invention will appear as Athedescription of also an object of the invention to provide.

Slidably mounted on thebase 11 is afjaw'meniber 14,

said `jaw member 14 also being provided with a curved inner face 15 thatis substantially semi-circular. Thel ja .w`rnember .12 has outwardlyextending end portionsfl' .in which are secured in any suitable, mannerthe guide pins 17v and the jaw 4member 14 Ais y provided withextensionsA 18 e which are adapted toslidably receive the pins 17, whichpins act as guides for the .jaw-member 14 as it member 19 provided witha flattened portion 19 is pivotally mounted on the upper is movedlbackward andforwardg `on the .upper` face of the base 11. A .cam

'withy a handle 20for operating. thewsame. ,l

It will be Iclear that when the cam 19 is lin the position shown in Fig.2 ,the jaws l12 and 14 `will be forced toward each other to hold amember, such as thejpiston 21 shown in Fig. 1, therebetween... i

In order .to make it possible to use thevise for v.various size pistons,lining membersor v collars 22 are-providedthat tit onthe interior` ofthe jaws and areof such inner curvature as to properly fit the outercurved surface of the piston 21. The collar comprising the member 22 isprovided with an inner facing of any suitable soft material, such asfelt fibre or leather, to prevent `marring of the piston.` l

vin place.

In order to provide for the return of the jaws to an open position whenthe lever is moved to a position at right angles to that shown in Fig.2, coil springs' 23 are provided on each of the pins 17, which coilsprings may directly engage the projecting portions 16 and 18 on theiropposed flat faces or plates, such as the plates 24 shown in Fig 2,

may be mounted between the ends of thel coil springs and the flat facesof the portions 16 and 18. The plates 24 extend inwardly beyond thecurved surfaces of the jaws 12 and 114 and engage the end portions ofthe members 22 so as to hold the same in engagement with the jaws 12 and14. The pivot pin for the cam member 19 is made with a central bore 25adapted to receive the stem y'26 of a valve 27 and is hardened for apurpose that will be presently eX- plained.v The lower end portion ofthe'bore 25 is provided with a'iiared mouth 25 so that the stem 26 maybe .more readily inserted therein. The upper end portion of the pivotpin 28 is provided with a flange 29 which bears on the upper surfaces ofthe cam 19 'and the lower end of the pin extends through theenlargement30 formed onthe forward end of the basevll. The enlargement30 is also provided with a suitable screw threaded opening to receivethe set screw 31, which is provided with a suitable handle 32.forturning the same, and the pivot pin 28 is provided with an opening inalignment with the set screw 31. They set screw 31 serves the purpose ofpreventing the pin 28 from turning in the base 11 and also holds the pin28 The set screw 31 also serves the purpose of hol-ding the valve stem26 in any desired position within the hollow pin 28. The purpose ofproviding the hollow pin is to provide a guide for filing the endof theAvalve stein 26 oft' square' as 'the pin 28 and flange 29 are hardened.All that is necessary in order to file off the end of the valve stemisto set the pin 28 in the desired position with the set screw 31 and thenle off the projecting portion thereof untilv the same is flush with theupper surface of the iange'29, after which `it will be impossible tofile further as the'flange 29 ishardened. The rear portion of the viseis provided with Va boss or projection-33, which is provided with ahorizontal :bore 34 and a vertical bore 35. Iithin the llatter bore is Imounted to slide vertically apin 36 provided with a pairofcircumferential grooves v37 and 38, and mounted within the horizontalbore 34 is a coil spring 39 Aand a ball bearing 40, the ball beingadapted to be pressed into either the grooves 37 or 38 by thepressure ofthe spring 39A thereagainst. It is, of course, un-

rdei-stood that the opening 34 is closed at 'the outer end by means of asuitable plug 41. The strength of the spring 39 is such that the pinwill be held in either the vposiposition shown in Fig. 7 to that shownin Fig. 1. The pin 36 is used as shown in Fig. 7 in which there is showna reverse gear 42 suitably mounted between the jaws 14 and .12, a splitring 43 being interposed between the jaws of the vise and the pinion 44on the reverse Vgear to hold the same firmly `within the jaws of thevise. If nothing were provided to lprevent vthe reverse gear fromturning in the vise, the reverse gear would turn in the collar or splitring 44 when operated on by a reamer or similar tool.

In order to prevent the turn-ing thereof the pin 36 is raisedto theposition shown in Fig. 7, when the pin will engage'in one ofv v sure onthe pin 36 it can be forced from the i the openings 45 between thespokes formed in the web portions 46of the member 47 of the reverse.,gear, thus rholding the same from turning. 4lVhen the vise is used forother purposes, thepin36 is moved to the v positions shown in Figs. 1and 3.

In Figs. 3 and 4 the vise is shown clamping a cam shaft bearing` 48suchas is used in a rFord automobile.v The cam shaft bearing 48 is made inonel piece as willbe clear from Fig. 4, andis provided with V-shapedgrooves 49 that extend nearly entirely through the material ofthebearing at diametrically opposite points. It will be evident that ifsuch a bearing as that shown were placed in an ordinary vise the samewould be very easily bent out of shape due to the weakened portions at49. The purpose for providing the weakenedportions at 49 is to make itpossible to separate the twoha'lves of the'bearings as'they would .bewhen put is usually necessary to reain out the inside of the bearingsbefore putting the same 1n place, as these are made a trifle .smallinthe factory. ,y i

In orderto do this reaming it isnecessary to provide means for clamping`thebearing without distorting the same. i 4

, In Figs. '3 and 4 the bearing 48 is shown as being provided withsuitable meansfor holding the same, and in Fig. 3 the leamer 50 is shownin position therein. The holding means forv the bearing comprises acollar made up'of the two portions 51k and 52,

yin use by a blow ofv a hammer. However, it

which collar is providedwith a bore in the upper portion thereof largeenough lto. re-l ceive the bea-ring 48, and at the lowerend thereof witha smaller bore 53 large enough for the reamer 50 to passtherethrough anda ledge 54 is provided upon 'which the bearing 48 is adapted to rest.The lower end por tion 55 ofthe collar is made small enough to passthrough the opening 56 in the face so that the offset portion 57 mayrest suitably upon the upper surface of the base member' l1. The upperportion of the collar 5l is provided with afcircumferential groove 58within which the split ring 59 is adapted to lie. The ring 59 is made'of resilient material, and is adapted toLold the members 52 and 5l inassembled relation, but permits the same to be spread enough to receivethe bearing 48. The collar comprising the members 5l and 52'is suitablymounted between the jaws of the vise and suitable bushings or liningmembers 22 are interposed be? tween the jaws 14 and 12 and the members5l and 52 so that the same will properly fit within the jaws of thevise.

In Figs. 5 and 6 the vise is shown as being used for holdingthe bearingcap 60 inposition while filing the same, the file being shown at 61. Thedevices for holding the bearing cap 60 comprise apair of members 62 and63 which together forma block having a circular outer face adapted tofit withn in the bushing or ring portions 22, which have an externalcurvature fitting that-of the external curvature of the' jaws l0 and 14.The members 62 and 63 are the halves of a block which together form avcentral recess 64 which is adapted to receive the upwardly curvedportions 65 ofthe bearing cap 60, the recess '64 being provided withlaterally extending'portions 66. "The block portions 62 and 63 are eachprovided with a vertical bore vadapted to receive one of the legs- 6T ofthe U-shapedresilienty member 68, the resilient member being adapted tohold the two halves of the block in assembled rela# tion, and theeXtreme end portions 69 thereof extend upwardly beyond the upper flatfaces of the blocks62 and 63 'tobe received within the bolt openings 70in the bearing cap 60 to hold the same firmly in position upon theblocks 62 and 63 while filing the same as shown in F ig. 5. As themembers 62 and 63 forming the block are securely clamped within thevise, and as the portions 69 holdy the member 60 firmly in position, andas the 2. vise of the character desc-ribed`com-- prising a base, a pairofjaws on said jbase, one of said jaws being movable relativelyftov`said base, ay pivot pin provided with a longi tudinal bore mounted onsaid base, and a cam for moving said j awmounted 4on said' pivotpin,`said pivot pin being adapted to receive a valve stem thereinandhaving a hardened top surface wherebv the same serves as a guide forfiling the same.
